Previous: Approaches to Customization
Given the personal database, as described above,
we will assume that a user identifies the need for
a couple of customizations:
- When inserting the address of a person in some textual
context, the user gets an error message if
the database contains more than one record on the same name
(``the name is ambiguous''). We want to change
the behavior such that each of the possible addresses is
presented for the user, and such that it is the user who decides which of
them to actually insert.
- The telephone company changes the area codes in
a systematic manner. When asking for a phone number
we would like to transform old area codes to
the new ones.
